Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed August 2'7, 1904. Serial No. 222,373.

To all whom it may concern:

Be it known that I, GEORGE W. STINE- 13RING, a citizen of the UnitedStates, residlng at Shreve, in the county'of Wayne and State of Ohio,have invented certain new and useful Improvements in Sawmills, of whichthe following is a specification. I

My invention relates to improvements in sawmills and it has for itsobject to provide a generally-improved device of this class which willbe exceeding simple in construction and efficient in use and which shallbe better adapted to its intended purposes than any other device of thesame class with which I am acquainted.

The paramount object of the invention is to provide a simple andeflicient carriage-feed mechanism for sawmills whereby the carriage maybe moved forward at any desired speed of travel, to feed the material tothe saw, and then to instantly and expeditiously return the carriage andmove or set the material over for the neXt cut.

IVith these ends in view the invention consists in the novelconstruction, arrangement, and combination of parts hereinafterdescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claims.

Referring now to the drawings forming a part of thisspecification,Figure 1 is a top plan view of my improved mill. Fig. 2 is a sideelevation with one of the side beams removed to more clearly show thecarriagefeed mechanism. Fig. 3 is an end view of the gear-wheels of theset-work mechanism. Fig. 4 is a side view of the same, partly insection, with operating-handle attached. Fig. 5 is an end view of thecarriage with setwork mechanism attached, two of the end pinions of thesame being removed. Fig. 6 is a detail view of the cable attaching andtightening device. Fig. 7 is a detail view of a movable bearing providedwith an operating-lever. Fig. 8 is a perspective view of a movablespherical bearing formed at one'end of one of the shafts: Fig. 9 is adetail view of a friction-disk and friction-wheel mechanism. Figs. 10and 11 are detail views of the cable attaching and tightening device.

Similar numerals of reference designaet corresponding parts throughoutall figures of the drawings.

In the accompanying drawings, 1 designates the saw-frame, upon which ismounted the saw and carriage-feed mechanism hereinafter described.

2' designates the saw-shaft, mounted in the usual manner in suitablebearings 3, secured to the top of the saw-frame and provided at one endwith the saw 4 and at the other with the main driving-pulley 5.

6 designates a small bevel-gear mounted upon the saw-shaft 2 and securedthereto by means of a set-screw or in some other suitable and convenientmanner.

7 designates a second shaft mounted at one end to the saw-frame by meansof a bearing 8, consisting of a main or outer block or bearing and asecond or inner block or bearing 9, the outer contour of which isspherical in form and which is provided with a central opening adaptedto contain and form a bearing for the shaft 7. It will be seen uponreferring to Fig. 2 that the shaft 7 is hung in an inclined position,and the lower end of the shaft 7 is eccentrically mounted in aneccentric block or bearing 10, provided with an opcrating-lever l1,pivotally attached thereto, and which said eccentric block or bearing 10is mounted in a second block or bearing 12, formed at the lower end of adownwardly-extending depending bracket 13, secured at its upper end bymeans of a bolt 14 and braced at its sides by means of a bar 15,adjustably secured to a beam 16 of the saw-frame 1 by means of nuts 17.In this Way the lower end of the bracket 13 may be moved laterally asmay be desired, moving the shaft 7 with the inner block or bearing 9,above described.

18 designates a bevel-gear mounted on the upper end of the shaft 7 inany suitable and convenient manner and meshing with the small bevel-gearmounted upon the sawshaft 2.

19 designates a friction-wheel slidably mounted on the sh aft 7 andconsisting of two parts or plates bolted or secured together in asuitable manner and carrying leather 20 or other suitable materialinterposed between the same. The friction-wheel 19 is secured to theshaft 7 by means of a flange or other suitable device which takes into alongitudinal groove 21 formed in the shaft 7 and is moved longitudinallythereon by'means of a shifting block 22, slidably mounted, on aguide-rod 23, secured to the saw-frame 1 in any suitable and convenientmanner. The shifting block 22 is provided with two short arms or fingers24, which take into an annular groove or recess 25, formed with the hubof the friction-wheel 19.

V 26 designates a rod secured at one end to the shifting block 22 and atthe other or lower end secured to the operating-lever 11. It will thusbe seen that by moving the operating-lever forwardly or rearwardly thefriction-wheel 19 is moved correspondingly upon the shaft 7.

27 designates a shaft mountedin suitable bearings 28, one of which issecured to the sawframe and the other of which is secured to the beam 16and carryingupon one end a friction-disk 29, adapted to be engaged bythe adjacent friction-wheel 19, and on the other a pinion 30, meshingwith a gear-wheel 31, mounted upon the end of a shaft 32, mounted insuitable bearings, one of which in the present instance is secured tothe under side of one of the sides of the saw-frame and the other to theunder side of one of the beams comprised in the carriage-track to behereinafter described.

33 designates a winding spool or drum about which there is wound a wirecable 34.

34 designates a winding-spool split in two parts and suitablysecuredbeneath one of the knee-beds 37, (see Fig. 6,) between which are clampedthe ends of the cable 34.

34 designates a handle secured to the ends of the shaft 34", providedwith a ratchetwheel and pawl 34 and 34 respectively.

The cable 34 passes over pulleys 35, secured to cross-ties a near theends of the car riage-track 36.

37 designates the knee-beds,mounted upon trucks 38 and to the lowerportion of which is secured a clamping device 39, by means of which theknee-beds 37 are secured to the cable 34 and are moved forwardly andrearwardly upon the trucks 38, traveling upon the carriage-track 36.

4O designates grooved wheels mounted beneath the inner trucks 38 andwhich travel upon the flange-plate 41, mounted upon the top of thecarriage-track 36 adjacent to the saw-frame 1. In this way the trucks 38are always held securely upon the carriagetrack 36.

42 designates knees of the usual construction slidably mounted upon theknee-beds 37 and moved upon said knee-beds 37 in the usual manner bymeans of a shaft 43, provided with pinions which engage a rack (notshown in drawings) formed on the under side of said knees 42.

The operation of the carriage and carriagefeed mechanism is as follows:hen the saw is running, the friction-wheel 19 may be moved on the shaft.7 to a point opposite the friction-disk 29 by means of the operatinglever 11, and by moving the lever 11 out wardly, turning the attachedeccentric bearing 10, the same will move the shaft 7 inwardly in anopposite direction to that in which the lever 7 has been moved, bringingthe friction-wheel 19 into engagement with the friction-disk 29, whichin the position shown in Fig. 1 will revolve the same and the connectedcarriage-moving mechanism, moving the carriage and feeding the materialto the saw. To decrease the speed of the carriage-feed, thefriction-wheel 19 is moved rearwardly on the shaft 7, bringing thefriction-wheel 19 nearer to the peri hery of the friction-disk 29 anddecreasing tfie speed correspondingly. To return the carriage, thefriction-wheel 19 is moved forwardly to a point beyond the center of thefriction-disk 28, and the speed of the movement of the carriage may beregulated in the same manner as in the forward movement of the carriage.

44 designates a ratchet-wheel securely at tached to the shaft 43 anddesigned to be operated by means of an operating-lever 45, pivotallyattached to the shaft 43 adjacent to said ratchet-wheel 44 and providedwith a series of pawls 46, which engage the ratchets 47 of theratchet-wheel 44 when the lever 45 is moved forward.

48 designates a pinion loosely mounted on the shaft 43 and designed tobe engaged and turned by a clutch 49, mounted on the shaft 43intermediate the same and the ratchet wheel 44 and normally held inengagement with the ratchet-wheel 44 and out of engagement with thepinion 48 by means of a coilspring 50, interposed between the same andsurrounding the shaft 43. The clutch 49 is provided with a key or flange49, which takes into the recess 51, formed in shaft 43, and is adaptedto be moved laterally thereon and into engagement with the pinion 48 bymeans of a plunger 52, suitably secured at the side of theoperating-lever 45. Said clutch 49 is moved laterally by the downwardthrust of the wedge-shaped plunger 52, operated by a rod 53, securedthereto and connected at its upper end to an eccentric head 54,pivotally mounted at the side of the operating-lever 45 and operated bymeans of a short arm or lever 55 formed therewith. 56 designates asecond pinion meshing with the pinion 48 and securely mounted on one endof a short shaft 57, mounted in any suitable manner.

58 designates a third pinion secured on the other end of the shaft 57and meshing with the cogs 59, formed about the inner periphery of theratchet-wheel 44.

60 designates a handle-bar attached to an eye 61, formed with the lever55 of the eccentric head 54 and designed to operate the op crating-lever45 and eccentric head 54 with its connections by twisting the same.

When it is desired to return the sliding knees 42 upon the knee-beds 37,the eccentric head is operated by means of the lever 55 or a twist ofthe handle-bar 60, and the plunger 52 is thrust downwardly, moving theclutch 49 laterally into engagement with the pinion 48, and it will thusbe seen that as the ratchet-wheel 44 is moved forward by means of theoperating-lever 45 the pinion 48, having engaged the clutch 49, (and theclutch 49 being out of engagement with the ratchetwheel 44,) the shaft43 will be caused to revolve in an opposite direction and return thesliding knees 42, as desired.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departingfrom the principles orsacrificing any of the advantages of this invention.

Having thus explained the nature of my invention and described a way ofconstructing and using the same, although without having attempted toset forth all the forms in which it may be made or all the modes of itsuse, I declare that what I claim, and desire to secure by LettersPatent, is
